Newtons 1st Law

Front

What is Newton's 1st Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by a net external force.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What happens to a coasting object without a force acting on it?

Back

It will continue to move in a straight line indefinitely.

Front

What is a force?

Back

A push or pull that can change the motion of an object.

Front

What is the relationship between mass and inertia?

Back

The greater the mass of an object, the greater its inertia.

Front

What is a balanced force?

Back

Forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

What is an unbalanced force?

Back

Forces that are not equal and opposite, causing a change in motion.

Front

Give an example of Newton's 1st Law in everyday life.

Back

When a car suddenly stops, passengers lurch forward due to inertia.

Front

What is the net force?

Back

The overall force acting on an object when all the individual forces are combined.

Front

How does friction affect motion?

Back

Friction is a force that opposes motion, causing objects to slow down or stop.
